How Can I Redirect Login Page If Do Not Login In Yii Framework?

I have the actionLogin and create cookie like here :




public function actionLogin()

    {

        $this->layout = 'login';


        $model=new LoginForm;


        if(isset($_POST['LoginForm']))

        {           

            $model->attributes=$_POST['LoginForm'];

            if($model->validate() && $model->login()){          

                $cookie = new CHttpCookie('loginSuccess',$model->username);

                $cookie->expire = 604800;

                var_dump($cookie);exit;

                Yii::app()->request->cookies['loginSuccess'] = $cookie;         

                $this->redirect('/ktbeauty/index.php/categories/index');

            }           

        }


        $this->render('login',array(

            'model'=>$model,

        ));

    }

And Now I have some controllers which must check to login before access controllers, if not login, it must redirect to login page, how can I work for this ?

thankyou very much
